Challenges

• SunCable set out to develop the world’s largest and most complex integrated transmission, renewable energy and battery storage facility. 

• To build the facility, SunCable needed to navigate complex regulatory approvals across Australian, Indonesian, and Singaporean jurisdictions. 

• This undertaking would ensure the sustainability and financial viability of long-distance power transmission from Australia to Singapore. 

• SunCable needed a partner to help implement state-of-the-art HVDC technology over vast distances and assist in overcoming technical hurdles. 

Solutions

• Implemented cutting-edge HVDC technology for long-distance power transmission.  

• Assisted in the design and delivery strategy for the end-to-end high-voltage transmission system. 

• Leveraged our extensive regulatory expertise to advise on regulatory approvals within three major jurisdictions. 

• Utilized +/-525 kV HVDC Voltage Sourced Converter system for efficient power transmission. 

• Supported the project with our global Environment and Sustainability team's expertise. 

Highlights

• 6 GW of renewable energy and up to 6 GW of transmission to match the ultimate generation and optimize the line's carrying capacity.

• Provided the most sustainable and financially viable means of transmitting bulk power over long distances. 

• Minimized transmission system losses and corridor requirements by implementing state-of-the-art HVDC technology using grid forming techniques.

• Enabled the transmission of up to 1.75 GW of renewable energy from Australia to Singapore.

• High voltage cable facility: 

First facility of its kind in the southern hemisphere 

One of the largest currently being considered for development globally. 

Features a 185m tall concrete tower for a vertical manufacturing process.

• Completed a scoping study and FEL2.
